The TURCK B8251-0 is a feature-rich passive interface module engineered to combine signal distribution, dual power routing, and status monitoring into a single compact DIN-rail unit. It offers 12 channels with integrated LED indicators for real-time signal diagnostics, along with a common ground and dual power bus lines that streamline auxiliary voltage distribution. This dual-power capability allows separate routing of +24 V and ground across multiple devices, significantly reducing wiring complexity and improving the efficiency of control cabinet layouts. Each channel is equipped with an LED to provide immediate feedback on signal status, simplifying setup, inspection, and maintenance workflows. With durable screw-type terminals and a slim DIN-rail-compatible profile, the B8251-0 is ideal for industrial PLC applications, sensor-actuator interface points, and modular control panels demanding both high connectivity and operational transparency. Key Features: • 12 signal channels with LED status indication • Integrated dual power bus – for +24 V and GND distribution • Common ground for simplified sensor/actuator wiring • Passive signal routing – no electronics or programming required • Screw terminals ensure secure, vibration-resistant connections • DIN rail mountable – optimized for space-limited enclosures • Enhances diagnostic visibility and wiring efficiency • Suitable for PLC panels, machine builders, and distributed I/O systems
